Fluctuations in PM10 readings are typically not a sign of a device malfunction but are rather influenced by environmental factors and the sensor's operational method.
Here are the primary reasons you might be seeing this behavior:
PM10 includes larger airborne particles that are common in any home. This category includes dust, mold spores, and pollen. The concentration of these particles can change rapidly due to activities like cleaning, opening a window, or even just walking around, which can stir them up into the air.
The sensor does not provide a continuous, real-time data stream. Instead, it operates on a periodic sampling basis, updating the measurement approximately every 10-15 minutes. This means you will see the data update in distinct intervals, which can appear as sudden jumps or drops rather than a smooth, continuous line.
The sensor is highly sensitive and may occasionally be influenced by other common household aerosols or high humidity, which can temporarily cause an inconsistent reading.
In summary, it is more useful to observe the long-term trend of your PM10 levels rather than focusing on short-term fluctuations. The purifier is designed to effectively manage these spikes and maintain excellent overall air quality.
